论文摘要
我们提出了一个劳动力市场部门自我选择模型，该模型将比较优势（如Roy模型和部门组成的偏好）结合在一起。两组基于每个部门的异质潜在收入和组组成之间的选择。潜在的收入结合了群体特定的人力资本积累和工资歧视。组成偏好被解释为反映群体特定的便利性偏好以及同质性和对少数群体状况的厌恶。我们表明，职业隔离是通过组成的偏好扩大的，我们强调了重新分布和多样性之间的张力。该模型还展示了从极端构图到更加平衡的倾斜度。当与平权动作相关的小动物将系统推向非常不同的平衡时，并且当均衡集突然变化时，当均衡的相对重要性越过阈值时，就会发生小费。
We propose a model of labor market sector self-selection that combines comparative advantage, as in the Roy model, and sector composition preference. Two groups choose between two sectors based on heterogeneous potential incomes and group compositions in each sector. Potential incomes incorporate group specific human capital accumulation and wage discrimination. Composition preferences are interpreted as reflecting group specific amenity preferences as well as homophily and aversion to minority status. We show that occupational segregation is amplified by the composition preferences and we highlight a resulting tension between redistribution and diversity. The model also exhibits tipping from extreme compositions to more balanced ones. Tipping occurs when a small nudge, associated with affirmative action, pushes the system to a very different equilibrium, and when the set of equilibria changes abruptly when a parameter governing the relative importance of pecuniary and composition preferences crosses a threshold.
